Uterine rhabdomyosarcoma complicated by cerebral venous thrombosis and uterine inversion in a young woman: case report and literature review

Background Uterine rhabdomyosarcoma is an extremely rare malignant tumor that usually affects young women and has a poor prognosis. Case presentation A 19-year-old nulliparous woman presented to the emergency department under sedation due to seizures. Imaging examination revealed cerebral venous thrombosis. During thrombolytic therapy, she developed vaginal bleeding followed by uterine inversion secondary to uterine rhabdomyosarcoma. The inverted uterus was mistaken for a cervical tumour and was removed vaginally. The patient's disease progressed despite chemotherapy with vincristine, actinomycin D and cyclophosphamide and she died within 6 months. To our knowledge, this is the first case of uterine rhabdomyosarcoma complicated with cerebral venous thrombosis. Conclusions Malignancy is an important diagnostic in patients with cerebral venous thrombosis with no obvious cause. This case demonstrates the importance of considering uterine neoplasms in the differential diagnosis of adolescent girls with abnormal uterine bleeding. Further, careful anatomical evaluation of vaginal masses should be performed prior to surgical intervention.
